JAMES B. T. WILSON, OF CHESTER, SOUTH CAROLINA.

AUTOMATIC MEASURING AND STOPPING DEVICE.

To all whom it may concern:

Be it known that I, JAMES R. T. WILSON, a citizen of the United States,residing at Chester, in the county of Chester and State of SouthCarolina, have invented certain new and useful Improvements in AutomaticMeasuring and Stopping Devices, of which the following is aspecification, reference being had to the accompanying drawings.

This invention is an improved measuring and stopping device for use onfly frames, roving machines, cotton spinning machines, etc., forautomatically measuring the number of yards of roving or yarn wound onbobbins and stopping the machine when the predetermined number of yardshave been wound.

The primary object of the invention is to provide a simple and effectivedevice of mechanism of this character which will not be affected bytaking up or slacking ends, or changing the tension gear, theconstruction being such that the use of the device will enable anynumber of frames of the same hank roving to be knocked oft with the samenumber of yards on all the bobbins.

Another object of the invention is to provide a device of this characterin the form of an attachment which may be readily applied to the rollerbeam and driven from the front steel roll, but which may also be appliedto other parts of the machines and driven from the main shaft, the topcone shaft, the spindle plate shaft, or the bobbin shaft.

WVith the above and other objects in view, the invention consists of thenovel construction, combination and arrangement of parts, hereinafterfully described and claimed, and illustrated in the accompanyingdrawings in which Figure 1 is a view illustrating the applicat-ion ofthe invention to a slubber roving machine. Fig. 2 is a rear elevation ofa portion of the machine showing the invention applied thereto, partsbeing broken away and in section. Fig. 3 is a vertical section taken onthe plane indicated by the line 3-3 in Fig. 2. Fig. 4 is a top planView. Fig. 5 is a detail section taken on the plane indicated by theline 55 in Fig. 1.

WVhile my improved measuring and knock-off motion 'or device may be usedon fly frames, roving machines, cotton spinning machines and the like, Ihave illustrated in the accompanying drawings the Specification ofLetters Patent.

Application filed May 9, 1910.

Serial No. 560,110.

preferred embodiment of the invention, and it is in the form of anattachment applied to a slubber roving frame.

In the drawings 1 denotes the main frame on which is mounted a rollerbeam 2; 3 denotes the front steel roll, and 4 denotes a horizontallydisposed shifting bar or member which is adapted to shift a driving beltfrom a tight to a loose pulley (not illustrated) or to otherwise controlthe stopping and starting of the machine.

My invention comprises a spring-actuated means for shifting the bar 4:,a catch for holding the shifting means inoperative, and a releasingmeans for the catch actuated from the front roll 3 or other part of themachine. When the roll 3 is employed for this purpose it is providedwith a worm 5 which meshes with a worm gear 6 fixed to one end of ashaft 7 the latter being here shown as mounted in bearings on a bracket8 fixed to the roller beam 2. Fixed to the shaft 7 is a beveled gear orpinion 9 which meshes with a beveled gear 10 on a shaft 11 journaled inbearings 12 on a supporting member 13. The latter is here shown in theform of a plate vertically disposed and depending from the rear side ofthe beam 2, to which latter it is secured by bolts or fastenings 14.Arranged on the shaft 11 is a worm 15 which meshes with a worm gear 16mounted on a stub shaft 17 adjustably secured to the plate or member 13.The worm gear 16 is adapted to serve as the measuring wheel and it isremovably mounted on the adjustably mounted shaft 17 so that it may bereplaced by a similar gear of different size for the purpose ofdetermining the number of yards of roving or yarn to be wound on thebobbins at one operation of the machine. The shaft 17 has its inner endadj ustably clamped by a nut 17 a or other means in a slot 13 in theplate 13, see Fig. 1. By constructing the device in this manner so thatthe gear 16 may be quickly changed, the machine may be set toautomatically wvind any predetermined number of yards of yarn on thebobbins. Fixed to the gear 16 is a pin 18 adapted to engage and actuatea cam 19 loosely arranged on the shaft 17 and adapted to in turn engageand actuate a latch lever 20. This lever controls a knockoff or shiftinglever 21 which is vertically disposed so that its upper free end engagesan adjustably mounted stop 22 provided on the shifting bar or member 4:.The intermediate portion of the lever 21 is fulcrumed on a stub shaft 28which is horizontally adjustable in the supporting plate or member 18 byclamping it in a horizontal slot 24 formed in said plate, see Fig. 4.The lever 21 is actuated in one direction by a coil spring 25 arrangedon a guide rod 26 which has one of its ends pivoted to the lowerextremity of the lever 21, and the other end of saidvrod slides throughan opening 27 in a support 28 which may be one of the standards of themain frame. The latch lever is horizontally disposed and has one of itsends pivoted at 29 to the lever 21 adjacent the fulcrum 23, and theother end of said lever 20 is slidably arranged in a slot 30 in of thelatch lever.

In operation it will be seen that the motion of the front steel roll 8will be imparted to the shafts 7, 11, and hence to the measure gear orwheel 16, and when the latter makes a complete rotation, the pin 18 onit will slowly elevate the cam 19 until the latter lifts the latch lever20 and disengages its shoulder 31 from the support 28. When thishappens, the spring 25 actuates the knock-off lever 21 and the upper endof the latter being engaged with the stop 22 shifts the bar 4 whichthrows the driving belt of the machine from the tight to the loosepulley, thereby stopping the machine. After the machine has been doffedthe parts may be reset by lifting the latch lever 20, returning the cam19 to normal position, and then shifting the lever 21 to place thespring 25 under tension and to engage the shoulder 31 with the support28, as shown in Fig. 2.

From the foregoing it will be seen that my improved knock-off motion andmeasuring device is actuated from the front steel roll and is entirelyfree from connection with the cone rack so that its chief advantage overother similar devices is that it will knock the machine off with thesame number of yards on all of the bobbins except where ends or strandsof cotton are left down, or roving stretched on account of heavy stock.

I have found in practice that the use of the invention will elfect thesaving of from 10% to 20% in labor necessary to operate the ordinary flyframes and roving machines; that it will increase the production of themachines using the roving taken from machines equipped with my devicefrom 4 to 5%, since there will be fewer ends down on account ofsinglings made, making it pos sible for the operative to keep his frame,or machine, running more regularly; that it can be creeled faster andeasier; that it will improve the quality of the work from 10 to 20%, asthere will be fewer ends to be pieced in back of creel, thus eliminatingmany thick and thin places in stock as it is impossible to piece ends ofroving together without making thick or thin places, and of course thefewer piecings made, the better the quality of stock produced; that itwill reduce the waste from creeling 50%, and there will be 50% fewerpieces to be run up a second time; that it will produce uniform rovingso that the roving of the same hank from any number of machines may beplaced in a single machine and have it run out even, the same as if allof the rovings had been taken from one frame.

In the practice of my invention I prefer to provide with the attachment,the shift rod 4 which takes the place of the usual shift rod on themachine.

lVhile I have shown and described in detail the preferred embodiment ofmy invention, I wish it understood that I do not limit myself to theconstruction, and arrangement of parts set forth, since changes andvariations may be made within the spirit and scope of the invention.
